My local tool store has a sales brochure for Jet / Powermatic equipment that is on sale for four days only. On the list, there's a Jet dust collector, 1.5 HP with a 2 micron cartridge filter, for $449. (Woodcraft also has this unit on sale same price, think it's a Jet / Powermatic promotion). My question is this - how good of a deal is this, do I stretch and get it, or do you guys think I'd find another similar / better unit on sale for a comparable or lower price in the new year? I just upgraded to a new table saw, so I'd be stretching a bit to buy this if I do.

I should mention that I have allergies, so I'm really set on something that has a decent filter - some of the bag units that filter to 30 microns really don't do much for me. I'm currently using a shop vac with a upgraded filter for dust collection, and it just isn't cutting it that well.
