D1 priced 2000 lower than Marquis while the Caldera is a thousand more than the d1-compable size, jets, warranty both Marquis and Hot springs dealers are nearby while D1 80 miles away. Free service calls locally versus $75 dollars for travel expense. Wet tested Marquis and Caldera, not the D1. Money aside loved the Marquis but 2 grand is over my budget and like the features of the D1, any advice for a 1st time buyer?
