i have a korg px4 and form what i understand the difference between it and the 4d is that korg combined the guitar and bass px4 into one unit. I bought a px4 when i first started playing and eventually I grew out of the amp modeling and wished the effect parameters were more adjustable but i still use it frequently becasue of its portability. In terms of pricing i would pay $140 for a used one in like new condition but ive seen new px4d's for cheaper than that so id go with one of them.
