Would you say they are priced reasonable compared to protocase/other fabs?
Yes, their price is MUCH better than protocase. Protocase wants about 8 times the price. A lot of that has to do with the volume order of 100 units though. If you were only having one made, I would recommend spending the extra money on Protocase as the process will be super easy to go from design to finished product. If you employ a standard fab shop, you'll have to interact with them on bend allowances/K-factors/bend deductions, etc. as well as what limitations they have for fasteners.
