I think you will find that the Resort has more power than the Epic. It uses the same pumps, has 7 fewer jets and does not have those geyser jets.
Pricing is dependent on the retailer. Some list at MSRP and discount off of that and others may have a lower list price that is non-negotiable. $1,500 is probably the least you will see for Microsilk. You can post your prices on here and we can give advice as to whether they are good or not. Hottubguy and Markee are Marquis dealers and I sold Marquis until last year. We can at least let you know how you are doing but keep in mind that just because Markee or Hottubguy sells a tub at one price does not mean your dealer will or is obligated to sell at the price another dealer does.
