It seems like the eGo cases are about the only e-cig dedicated cases out there. I've been looking all over and haven't found anything I really want. I'm to the point of branching out and looking around WalMart, Home Depot, etc. for stuff that will work. I bought a cheap set of plastic drawers for $9 for home storage, and have settled in with a padded Altoids tin for my spare carry items. It's not great, but it works for now.
How big of a case are you looking for, and what's the purpose (daily carry vs travel carry vs home storage, etc)?
Sorry, no help here with the drip tips. I'm happy enough with the standard plastic cheapies.
