I would recommend a KJW long before a WE and a TM over a KJW.
At the prices you've quoted I'd get the TM over the WE, IMO it's a no brainer. A WE should only cost you around $200, A KJW $250 and a TM $300+. The plastic slides on TMs are much more robust than people usually give them credit for. While not designed to run on propane they will hold up quite well to it's usage. A plastic slide will also cycle faster and consume less gas than a metal one. The slide MAY crack on you but it's only a $10 part.
