As for keyboards.
I feel like the AKAI keyboards offer much less. People say they are built well, but if you've ever taken apart any of these things they are all pretty much equal in quality. Wether it's an APC40 or an MPK, the faders on these products are known go bad, especially at about 2 years. You can get replacements at MPCstuff.com. Not everybodys, OR ALL faders, but chances are at least 1 will stop working after a couple years.
Personally I think the Novation SL stuff is the best bet.
Keys feel better than all others in it's class.
You have WAY more on board controls.
I dont care much for Automap, but the editor has always worked fine for me.
Here's an SL61 for under 300

As far as newer Novation keys with the Nocturn style knobs, it's good to know those knobs are crap, glitchy, and will not last over time.
I would take an older Novation keyboard over the newest ones any day.

These also have "function' buttons for fast template switching which is WAY AWESOME.
The APC40, is still a pretty great controller, besides all of it's funky built in behavior.
I say find a Novation keyboard for 100 bucks or so, then spend the rest on a launchpad and a Korg NanoKontrol. All for under 300.
