the question is, why do you want to switch? If you are able to do what you need to do, then spending money on new hardware and taking the time to learn new software is a bit of a waste...unless you like to spend money on new hardware and take time to learn new software.

As far as converters, it depends on what you are using now.

Are you more midi, more audio, or a mix? What track counts do you normally run? Do you use virtual instruments? Do you need to be in OSX now? All of these things go into choosing what system is best for you. PT is strong in some areas, weaker in others. Same with DP and Logic.
