I have a capresso that I use on occasion. The capresso is a perfectly fine grinder for anything coarser than espresso grinds (drip,french press, etc). You can do espresso grinds with it IF you back the torx screw out slightly on the Burr's (its very easy to do, takes less than a minute) it is capable of fine enough grinds to stop my Isomac Tea HX machine , however it is not going to be able to produce a very consistent grind for this fine of a grind which you really need for espresso(I have a baratza vario which is what I use for espresso). Also if you back the torx out, you will probably have to tighten it again to get coarse enough for press. I have heard ppl modding them so you can turn it past the stop, which would probably give you enough adjustment to do both.
Its not that its a bad grinder, in fact its more than sufficient for anything but espresso but it is one of the cheapest grinders that can be used for espresso (unless you consider hand grinders, some will also produce a good grind for espresso) so you cant really expect much its going to perform like a high end grinder. The pro-line is starting to get into the range of grinders that are considered acceptable for espresso, so of the 2 I would choose that one out of the two (unless you use a machine with a pressurized portafilter then you can probably get away with the capresso)
