Click detection at 0 isn’t on everyone’s wish list. Generally it causes some inaccuracy around the 0% mark due to mechanical issues. Personally I don’t mind either way, but I know a lot of DJs who like their pitch faders without indents.
Both SB and MTP are good controllers, as are Beatmix 2, MC2000 and (more expensive) MC4000. ALL of them are more than sufficient for starters. Some of the “problems” you mention can easily be solved by using some gear that you would need anyway if you start playing out for real (like a backup option through a small PA mixer, which will give you mic input and XLR output for example).
@Kenroy: While you are free to never want to buy any of those controllers, we appreciate if you would express your opinion rather than state things as if they are the hard truth. Statements like “all these entry level controllers are a joke” are not appreciated on these forums. They lead to needless “he said/she said” discussions and polarization. It also isn’t very nice towards the owners of such controllers of which we have plenty (trust me when I say your RMX is outnumbered a 1000 to 1) saying that the gear they own is a joke.
So, by all means contribute to the forum, give advice or your opinion, but do it in a way that follows the posting rules of these forums. Not following the posting guidelines WILL result in sanctions.
