go with totally wicked if you have lots of extra money to just throw away. I guess their attys are solid gold cause all their stuff is super expensive, plus shipping is high too. Id go with rockymountain or cignot. Same stuff as TW, cheaper, free shipping.
When they run a 30% off sale, which is about once a month, if you buy a box of 5 510 attys it comes out to about $5.50 an atty, which is very good. Only problem is there is no warranty for boxes of attys, and if you are new and like I was in the beginning, you tend to kill attys fairly often. Now that I know how to use and care for them better, which depends on many things learned over time, I am realizing that TW's 510 attys are very good indeed.
Always looking for sales to bolster the reserves. And like others said, be wary of copy-cat brands. If possible get only Joye. TW's Titans are rebranded Joye hardware. I love their mega batts, too. But I only buy hardware on sale...most companies inflate their prices in general, and only become reasonable when running a sale. The chinese sites I think are the exception. Their prices are generally lower, but they have less sales. I almost jumped on the 25 attys for $125 deal, but I have to make sure I can keep the heat on this winter first...or not...
