Also depends what you plan on driving with it? Lot's of jokes about blowing them up, so if you have time, research it, also look for similar designs of which there are many, see if your speakers and room/listening habits will work! It's kinda like getting a puppy if you will, you don't get a cute little Scotty and be at work for 14 hours at a time, match the amp to your needs and lifestyle. I have no idea what to offer for one, I've heard they sound very nice if matched properly and very well built.
Good Luck, Craig
