What is a GOOD hand held pump sprayer for weedkiller and pesticide??

[Complete Turf Care]

I have owned at least 20 backpack sprayers over the years. My crew uses them almost daily.

Solo is a good brand and is available in lots of places around here.

Jacto is another brand that I like. Products

I've had a few of the battery powered ones, but they just don't seem to last long enough for my needs.
