You are going to be really happy with the XP's. I have an XP3 on my 75g, and XP3 on my 55G, and an XP2 on my 29G, and all have been great. Have had almost no problems other than getting plugged up when I don't do maintenance on a regular basis, lol. As for the heaters, I use the Hydor ETH 300 heaters. They work awsome.
