Our Jacto has served us well.

Solo is a good brand. When you order it, go ahead and order the rebuild kit (and store it someplace where you can find it in a few years.)

AgriSupply carries two 4-gallon models, each $85. One is advertised to handle both liquid formulations, and wettable powder form.

Here's a good helpful link about sprayers, though it doesn't give brand analysis.

SHURflo SRS-600 $185 shipped from Ebay seller Turnkey. I know you said you didn't need a $200 BP, but if you plan to use it more than a handful of times in a year, spend a little more and get something that is a joy to use.

I need to do some spraying with chlorine solution (Jomax). Trying to decide between the SP Systems YardTender 189 and the Echo MS-40. Biggest differences:

Yardtender 189 has a 20" brass wand. MS-40 has a 16" brass wand.

Yardtender 189 warranty is 6 months. MS-40 warranty is 5 years.

Yardtender ships with adjustable brass nozzle and a fan nozzle. The MS-40 ships with fan nozzle.

The MS-40 is $10 cheaper, and has cheaper accessories. Been going back and forth as to which one to buy.
