Finally got one of my '91 G250's back from servicing. I have two identical regs. They are totally updated. I paid $150 for parts and service on my MK10/G250/G200. Tried it in a pool yesterday and compared it to my G260. The G250 is about as easy to breath as the G260. The air "delivery" has slightly different feel. The G200 is now a B and almost as good as the 250. Tried my friend's new Aqualung Legend too. I was surprised it seems to breath a little easier than both, again with a different "feel". Its the base model. I wouldn't bother buying a more expensive model, this reg is excellent as is. Also tried my new SP Go Sport fins. To me they blow away my Mares Quattro's. Way less fatiguing, feel more like part of my body.
