I will definately take a look there. Anyone reading this thread that has purchased thru ebay, let me know what luck you have had.

I went ahead and hard plumbed (1 1/2 inch pipe) the filter in anyway, and I did end up with a much better flow rate. (now the vacume actually works!!)

one question remains, what size set up should I look for ? 16", 20", 3/4hp, or 1 hp ? don't want to over do it...
any help appreciated!
