I’ve been collecting them for quite a while now, I wouldn’t consider myself an expert by any means, but I’m quite knowledgeable. If you like, shoot me a PM and I’ll have you over and you can test a few models out. If you’re new to this and are a little nervous, I’m absolutely willing to “lend a hand” and help you out. Show you how it’s done. The only stipulation is that you must be POZ.
