New to the forum with some questions...

Hello everyone! I just joined thid forum, but am not stranger to how a forum work I belong to many others. Just wanted to say hi and I had a couple of towing questions:

I am upgrading my brake controller because the one they put in when I bought my toy hauler sucks. I was thinking of either the tekonsha prodigy or the tekonsha P3? The trailer I tow is a 19' two axle toy box. I do plan on getting a bigger one in a year or two so I am taking that into consideration. Is there any advantages of one or the other? I found the P3 on Ebay for $20.00 more than the prodigy so wasnt sure it is worth the extra money.

The other question is that I am planning on adding some "helper springs" as well but can decide on the helwig units or the super spring units? I searched aroung the forum and only found people talking about the helwigs. Does anybody out there have the supers springs? Are they worth the extra money? I do also plan on lifting my truck in the future so will either of these springs NOT work after I lift my truck or will it not be a problem.

Sorry this is so long, I guess I had more to say than I thought. Well I hope this forum is as friendly and helpfull as some of the other ones I frequent. Thank you in advance for any help.
