i have an older cal spa with a cs3000 balboa spa pack. the spa has 2 :" title="Question" /> pumps, ozone and fiber optic lights. the controll panel worked it's way free over time and eventually rubbed metal to metal and fried the board. upon doing some window shopping i have found the spa i have requires a pack with all the input options and is expensive. there is a balboa 2000le with m-7 tech on e-bay for only $150. it comes with a basic topside that will only controll one pump. everything i've read says this panel will do everything i need but not with this topside. i've noticed the companies selling these on the net do not charge any more or less for the different topsides so i'm asuming the boards are all the same but it's the topside that makes them use what they are capable of. am i correct in my thinking? and what is the chance the cs3000 topside will work with the 2000le? if i buy this 2000le (it's new by the way and i know they sell for $600 or so) and then buy a balboa topside from someone else that will work 2 pumps it should all work together right?? any feed back will be app :" title="Question" /> reciated! missing the tub..........

No, this scheme doesn't work that way.

You need to get a system that'll work with your spa. But if you take a chance on ebay, and then get ebay tech support, well it's your money.

Well I hope you can get this working this way.

Post back when you get it going.
