Has anybody tried any alternatives to L3DT?

[HEW177]

Hi, I have been using L3DT and I am just finishing off my second track to release which will hopefully be an improvement over my first but I was wondering if anyone uses a different program to L3DT for the heightmap editing.. I know that some people use Photoshop or equivalent and I have looked up many alternative dedicated heightmap editors but I thought that I would ask on here before I download and test them all.. (I am happy with L3DT but would like a bit more fidelity and or tool adjustment maybe?! - I don't know if it can even be better tbh!)

Also, is there any benefit to L3DT Pro btw? I have looked into buying it but the purchase page is down and the 2 keys that I have requested for the trial have both said invalid.. (I have pasted the whole string in and no good.. I sent them a message)

Many thanks to TFC for all of the help with L3DT.. his tutorials made it a much easier and less daunting process!!
