I a, getting a older Spa, it is a Marquis. However, it needs a new spa pack. The Marquis dealer wants $600 for a new equipment pack. Do I have to use theirs or can I look around and get one from some where else cheaper? Also what is a good price and what should I be looking for in a spa pack.

I recently bought a Nu-Wave spa pack for my old hot tub, and the price was $625 including digital topside controls. By the time I got a new GFCI, blower safety valve, ozonator, etc, it was more like $900.
