I bought a TM TWCS throttle when they first came out to check it out and compare it to all the other HOTAS I have (all of them pretty much). I was very impressed with it for the cost - I got mine for around $100 ish CAD including shipping/tax/etc IIRC. I've seen them on sale @ Amazon USA for $59 + shipping/tax, so you may want to hunt around or wait for a sale. I think it's a better product than it's nearest competitor, the CH Throttle, very solid feel to the buttons, hats, wheel and so on. It has a bit lower and wider stance than the CH which I find fits where I rest my left arm on my gaming table surface too.
You can't go wrong with it, again, better quality, ergonomics, and overall value than I expected it to be. Have you thought about taking your WH throttle apart and seeing if there are any wires or connections that have failed? Lots of other forums and sources out there to give you advice regarding this.
If you're feeling spendy, Virpil announced yesterday that their new stand alone throttle has gone into production, and should be out shortly. $240 Euros, whatever they are, probably be around 300 bucks in real petro-chem dollars by the time you got it to your door. Sure looks nice though, they made quite a few changes to it as well based on community feedback, which wasn't stellar when they released their concept model. VKB has a really nice stand alone throttle coming too.
Lastly, another option is find a TM Cougar throttle, buy the USB adapter that's available for it that's around $20 USD, and use that. I find used Cougars online pretty much monthly, and have picked up a few in the last year when I find a good yet cheap example - ie $50+shipping for the last Cougar set, and it's in great shape, so that's another route you could take too. You can even mod the gimbal in the Cougar stick with an excellent setup that's around $50 IIRC.
Stick wise, if you check around you can find another TM Warthog stick only frequently too. I've got 2 that were "scratch/dent/damage" from Amazon, and they had literally nothing wrong that a black marker wouldn't fix, and were around 3/5 of a retail nw one. I've not tried any of the lower end stand alone sticks, but lots of others here report that the TM and some of the Saitek sticks are pretty decent in that regard. Also, VKB has a less expensive but still very good Gladiator too.
