We went last year and will not be going this year. You really need to know what you want to focus on before you go. It is huge - we had a list of 5-6 brands we were interested in on the first day and then really narrowed down to one or two the second day. First day was semi-focused, second day was very focused. Lots of opportunity to spend big $$$ if you're serious about buying. Some good deals, some not so good. Great place to compare units side by side.
And the crowds! And the parking lot!!! I'd say it is worth a trip once in a while but no way I'd go every year.
