Hi:

I am looking for a good, reliable, long-lasting back-pack weed killer sprayer. There are so many available on-line, but without looking and touching the valves and mechanisms it is hard to determine if the thing will last long. I bought several from Home Depot and OHS and they did not seem to last long.

Could you recommend a good one ? If you live in the San Jose, CA BAy Area, could you also recommend a dealer ?

Thanks a lot in advance.
