I need a good resin gun/pump

[juiceclark]

We're on a shoestring budget (of course) but building a 50 footer. So, I'm looking for a good value in a resin/gelcoat gun. The 2 gallon jobs are too small...need something to hook-up to the drum or at least a 5 gallon bucket.

Does anyone have a used one in good shape you want to sell? If you have some advice on the best product (or what to avoid) I'd appreciate that as well.

Thanks!
