I might get a little heat for this next comment, but I'm going be honest and say that Solaris is usually kinda high... like 50-100% over actual reasonable street price. Now if you need a product right away, sure it's great place to go. But if you have some time just wait and keep your eyes out. Do lots of research and find out exactly what you want. The worst mistake you can make is spring for something just because it's cheap. After you know what you want watch craigslist and eBay and it will eventually come around.
But I disagree with not buying a HOG II just because HES doesn't support them anymore. There are so many out there used parts will always be available, and almost everybody in that part of the industry knows them meaning it's not hard to find somebody to work on it/help you with it. It's a solid board, and like derekleffew pointed out, it was the industry leader for a long time.
My question to you, though, is what are you looking to do with this board? I noticed your occupation is listed as Undergrad--is this something you are looking into for your school, or personal use? I can tell you from personal experience that HOGs (any) just aren't useful for primarily
conventional rigs. My undergrad bought a HOG iPC just after they hit the market, which was really stupid because they didn't own any movers and shows didn't have a lighting budget to rent them. We ended up using our
ETC Expression 3 for every show while the iPC sat in the electrics shop.
