Yeah, the MyWallet sites are very tricky. First, the server needs to meet bootstrap requirements, which many of these faucets do not.
Second, the code is sloppy, so you need to re-work it. Only a few people have debugged their MyFaucets to handle the level of requests, and the server they are on.
Blud was working on his site for a bit. He debugged the hell out of it, even though it looks like a generic MyFaucet, it's not. He wants to be around for a long time, so we'll see. Very promising so far.
http://bludsfaucet.com/?id=65I use MyFaucet, it can indeed be very buggy/had issues, I fixed all that were noticeable and run smoothly now. but yeah, I could've better just made a script from scratch probably. On top of that, the script cost me 0.36BTC because it had a security leak causing funds to get stolen. That hurt my wallet a bit.
EDIT: This was a while ago and obviously everything has been resolved. I paid it out of my own wallet because they were donations and it'd only be fair.
