I was never real happy with the Warthog stick, I had a lot of issues with it. The Warthog throttle isn't bad, though I did replace mine with a Virpil throttle. I keep the Warthog throttle as a backup, the stick is in the junk pile.
I have one of the first Mongoos T-50 bases, that I replaced the Warthog stick with. Night and day difference between the two. You can adjust the feel of the Virpil stick, with springs and cams. Virpil recommends the Mongoos base if you plan on using a stick extension, and the Warbrd base if you don't. Although that's not a hard and fast rule. I have a squadie that uses the Mongoos base without an extension. The Mongoos base is also not made for table top use, it needs to be mounted, and because of the overall height of the base, and grip it needs to be mounted rather low. Nothing wrong with the Warbrd base, same sort of build quality as the Mongoos, it's shorter, has a bit more throw, and is a little cheaper.
Another option, as Bixby has already mentioned, is the VKB Gunfighter, I don't have one, but I would like to try one out. I have another squadie that does, and he likes it, as does everyone I've talked to that has one. VKB doesn't have a throttle in the Gunfighter series, they keep saying they're going to release one but so far nothing.
