I think the DIY route is a good one, depending on your abilities, you can get a fairly pre-made board from doepfer & attach (screw on) jack sockets for up to 16 pedals (or more with expansion), or you might look at an even more DIY solution if you are good at soldering & building stuff
one thing to look out for is the impedance... some generic pedals have an impedance matching circuit which would get round the problem of the board wanting 10k pots and the pedal having 50k ones (for instance)
all the best

For example with the Arduino.

I also use an FCB1010 with pretty good results.
Mine has never failed and I have used it extensively and travelled with it with no problem whatsoever.
My own experience with the expression pedals is very positive: not sure if I'm set up differently but the pedals are completely linear and they will give me nearly the whole range (probably around values between 5 and 127). I'm not sure I understand that 80% of the range giving 10% of the values comment. The exp controllers only use 7 bits and not 14, but I never found it to be a problem.
I have an FCB1010 abstraction that I've made. If it's useful to anyone, email me and I can send it to you.
On another note, I have had very good success building my own pedalboard based on an arduino. Right now mine has twelve carling momentary footswitches, and I'm planning to put in 6 jack sockets to connect expression pedals. The carling switches are not cheap (they cost me about £3ukp each) but they are very robust and they feel right to a guitar player. I had a metal fabrication company build me the casing from a drawing. The box is wedge shaped (lower towards me than the back) , and about 50cms long, 20cms deep, with two rows of 6 switches. That cost me about £60ukp. I'm very happy with it, and it responds better and faster in my estimation than the FCB1010. I loaded the arduino with HC Steiner's brilliant pduino firmware, and read the data with the pduino object.

I get almost the full 0-127 range out of the pedals, but the problem is that When a pedal is ca. 80% pressed towards the top of its range, the MIDI value output is only about 13 (~= 127 * 0.1). The remaining 114 values all seem to reside in the final 20% of the physical pedal range. It's a bit of a pain to work with since the "useful" values in the 13-127 range are clumped so closely together, and that makes the pedal seem overly sensitive to me.
I've read in another forum that such behavior is common among new-ish fcb1010 versions, and is a consequence of the the mechanical translation from the pedal position to the underlying potentiometer: since a rotary poti is used, the actual value plot ought to follow a sinus curve, but I haven't tested this systematically.
I have an FCB1010 abstraction that I've made. If it's useful to anyone, email me and I can send it to you.
I'm interested! In fact, I've written such an abstraction as well, which I'm also happy to share.
