One of my favorite all time basses, if not the #1 favorite, is the Hamer Chapparral 5 bass. Its simply the best thing ever built in the bass world.
There are a few things to watch out for with US Hamer guitars. They have this condition where their glue interacts with their finish product and causes the finish to fade, crack, or even peel off around the neck joint. I have seen it on several models I see for sale on Ebay, so you better look close there. That glue also can tend to loosen up and require a neck reset and reglue. I have heard of some of those also.
The other thing is that they seem to use a wierd input jack thats too small for alot of normal plugs on the market. Its something that can be really annoying when you buy the guitar sight unseen and get it in the mail then don't have a guitar cord that will plug in to it!
Just keep your eyes open out there and buy informed!
