I need to restain my house. I am using caot’s semi transparent stain. I would like to be able to spray it on, then back brush.
looking for an inexpensive sparyer that will do a good job of spraying the stain I will be using. I know the satin has some solids in it even when mixed super good.
I am looking at the Wagner site. Any one have any recommendations?

Have you looked at renting instead? You can get a much better tool renting that you would be able to afford buying.
Harbor Freight, Airless, $35.
Cheap enough?
Now ... let's get serious ...
I understand your desire to spray. I don't think you know what you're getting into. No problem, that's what this forum is for.
First off, what are the solvents in the stain? That will determine whether a 'normal' sprayer will be harmed. Generally, solvents that are 'combustible' are fine in the ordinary sprayer, while solvents that are 'hot' or 'flammable' are not. Mineral spirits are OK, lacquer thinner and acetone are not. Look at the MSDS for this information.
If your material is paraffin / wax based, consider buying a sprayer. Such materials are degraded by the sun, and good for only three years or so. The stain can will tell you this.
Next ... about spraying ... I cannot stress this enough: cover EVERYTHING - even stuff that is 20-ft. behind you, into the wind. Overspray will go everywhere. Maybe even rig up a 'tant' you can move along as you spray in sections. Get several head 'socks' and wear dedicated clothes, or even, a tyvek suit. Even a respirator isn't such a bad idea.
Don't overlook your cleaning operations, either. I find a 20-gal automotive parts washer (filled with the proper paint solvent) just about ideal for cleaning spray eqipment- though you will want to improve on the drain arrangement. It's good for cleaning brushes and rollers, too.
Personally, I would be biased in favor of the Graco Pro-Shot "Fine Finish" model, but that will set you back $700. I do not know if there is a corded version available. If you can use the standard Pro-Shot, prices will be substantially lower. Be advised that any of these sprayers are of limited life, needing a rebuild or replacement after about 50 gallons.
The "Pro-Shot" line is exclusive to Sherwin-Williams. Everyone else gets the similar "Tru-coat" line. Nozzles, tips, and expensions are not compatable between lines.
When spraying, it is helpful to have several extra paint cups ready. You can spray nearly three gallons before you our-pace the battery charger. One battery = 1 gallon. You'll also appreciate an extension for reaching high or overhead surfaces.
When finished, run some "pump armor" through the sprayer to protect the seals in storage.
Cheap Wagner sprayers will do about the same job as more expensive ones. Recent models should be better, but I would recommend extra tips. Paint can clog or dry out in the tip and you will want extras handy, especially with cheaper sprayers. When you are finished, each day, run solvent or water through to clean out everything. If manual says you have to disassemble the inner mechanisms (I think some parts of the pump) to clean at the end of the day, you should.
You may want more professional models, with bucket holder and long spray tube. These will make the job at least 100% easier, since your semi transparent stain will need frequent recoats. With professional models, I would skip the middle ground-cheaper models and plan to spend at least 5-600.00. Sorry can't be more up to date, but about 10 years ago, I heard Graco was good brand.
