I have purchased the 32 channel set up a few years ago when I switched from static to computer controlled. I have not had a problem with my set up for the last four years. As camper said there are cheaper ways to get the same product but for myself I wanted a set up that I had the chance to learn and build upon. The WOW set up really for me was plug and play to get it working then the sequencing was a hurdle but again there are tons of sequences that can be borrowed from users here and over on LOR and a bunch of other sights. They more than likely will not fit your lay out but are easy to fix up. I have since added 4 more controllers and 6 RGB universes. The more I work with the RGB lights I really like them and plan on moving more to all RGB. I still have a bunch of static so for me it is the challenge of making both fit and work together. A 128 is a bunch of channels to jump into at the first. The cord issue is for real you will need a bunch of zip line and vampire plugs at least 128 of each female and male. it might be a good suggestion to wait for the summer sale at LOR (Light O Rama). If you are not familiar WOW is a vender of LOR and to get a bunch more info go over to LOR and check out the forums there and you can find some units for sale also. I personally would stay away from the ebay and other for sale places seems there is a lot of people taking advantage of people. I would make sure you have a good back ground on the seller. You can ask here or even on LOR forum. The DIY boards are good also it really depends if you want to put the time in on all the soldering. Hope this was helpful and good luck.
By the way Welcome to the Madness
