I have been pretty happy with my Hudson Sprayers (2 gallon and 5 gallon). I wish they had service parts more readily available. I have not absolutely needed any parts but there are some gaskets I would like to replace.

I have not heard anything bad about Solo although I mainly only see backpack sprayers from them. I assume they make hand sprayers, I just have not seen them. They have been around for quite awhile.

Gilmour makes some awesome garden equipment and they have great warranties. I have had one nozzle replaced at no cost and am about to submit a 15 year old hose for comoplete replacement. No questions asked. I have not looked at their sprayers. If they are the same quality as their other offerings, I would consider them also, maybe even more so because of excellent customer support.

I think SP Systems was higher end stuff? Not sure about them. I think Flo-Master does make some higher end commercial stuff. I'd check out those before what HD offers, which I think is HO level.

I don't know the Yardtender name at all.

SP SYSTEMS yardtender 2 gallon I have is the best sprayer I have owned. I too have been unhappy with the sprayers you find at home depot. The Yardtender has a great wand, the hose is beefy and resists kinks, and the body/pump is solid. There doesn't appear to be a pressure relief valve but good!...no troublesome leaks. It can hold pressure an awefully long time and has a great wand/brass tip that you can exchange for many conventional spray tips from tee jet et al. I bought it for $80-90 but worth every penny.

I've had a Solo 2-gallon sprayer for 2-3 years; been great. I ESPECIALLY like that I can air it up with my compressor; after spraying about 1 1/2 gallons, I have to pump it some, or go back to the compressor. Gave about $40 for it at Northern Tool. Parts readily available.

Javert, which Solo did you fill up with your compressor? How did you do it? Is there a schrader valve on it? PSI?
