I have an old, OLD, OLD Cuisinart "Mini Prep Plus." It's the one with the sealed buttons, stainless in color. I think I've had it for 15 years - minimum.
I use it mostly for salsa batches. I make a LOT of salsa.
Not sure what your plan is for the new one. I also use it once in a while to puree sauces if needed. It's too powerful to trust things like getting a uniform dice, one pulse too many, and you'll liquefy, or mushify. For a mostly diced salsa, however, it works for me, and I'm way too lazy to dice all the stuff by hand - mostly because the mini prep does it just fine.
Anyway, seriously, this thing has been no trouble since day one except for a month ago, the little tab on the cover/lid that engages / disengages the motor lock snapped off somehow.
I've decided to ONLY buy another older one, if I see one pop up, OR a new lid. In the world of gadgets and doohickies that I've bought over the years, this stupid little thing has been rock freekin solid so much, that it's just one of those things I almost never even thought about dying when I grabbed it. And that's a good thing. Totally solid, never skipped a beat. And the motor is still rock solid, blade is still sharp as hell. One thing about it, and maybe same thing with all - cilantro stems, and probably parsley, too - you can't throw them in if they are too long, or a few will just wind up wrapped around the blade pole. Not a big deal. More than likely you'll have a chopping board and knife already because you gotta cut other things up to get them to fit in it anyway. So, I ALMOST threw mine out when the lid broke, but I figured out how to attach the lid and slide a thin object into the slot with the motor engage/disengage lever, Buys me some time to find a new lid or whole new unit on the cheap somewhere. Plus, it makes me feel all McGuyvery and cool as I watch my wife roll her eyes at me for not wanting to spend 40 bucks on a new one, but I'll easily buy 9 jars of strawberry habanero jam at 9 bucks a pop, just to have in the pantry in case the company stops making it.
