The obvious alternatives would be a Harrier and a Hornet but then there are also contenders from other makers such as Logun with its Solo or Gemini (if you are going used).
There are lots of choices in your price bracket, some used, some new.
I have had an S400, a Harrier X and a Hornet, all rifle length, all in 0.177.
I couldn't get on with the Harrier so it went to a good home, the S400 was utterly superb for me but I swopped it for an offer I couldn't refuse (Venom tuned TX200SR) and I now have the rifle length Hornet (tuned by Mr B). The Hornet is promising but the basic stock is pants (for me), it's too weedy at the front, too much wood where my thumb and palm go and the cheekpiece is too low, but it has got a sweet trigger and a very dead firing cycle.
As to the stock, well Mr Scott may be helping me out on that one soon.
Basic advice is as ever the best - go and try them, if it doen't fit / suit you there is no point in buying one. Given the capability of most modern PCP's (and springers) a 'bad' one that suits you will be much better for you than a 'good' gun that doesn't.
If you want to compete in HFT then you 'may' need to uprade your scope.
Just my opinions of course.
I play a Fender bass, I shoot a springer. I like things to be, well, dependable
