I have one similar to this one. I like the instant inch/metric conversion.
While I wouldn't rely on it for any really critical machining, mine has been very reliable and accurate.
The digital readout may be easier for people not used to the dial caliper.
I also don't have any particular recommendation for the seller, I just picked one in the price range of what I paid for mine that looked nearly the same. Other similar ones are available a lot of places for a bit under $20 to a bit over $40. One with a good brand name that would look better if you're doing serious machining will run around 2-300 But for most of us that's not necessary.
