Bought one of these and I can say its £170 well spent.

it was easy to put in / set up (see how to guide). it looks great and has a nice big display and two simple buttons to operate.

it uses open loop programming with duty cycle and gain and with a bit of playing about Ive got mine to spool up quickly with no spikes or overboosting and holds boost perfectly, either running standard or with gtec 1 (ive got the 4 settings set to 0.9, 1.0, 1.1 and 1.2 bar) it also "learns" your engine by reading back the boost results from the settings.

having had a play with a profec B - spec 2 I'd say this IBC doesnt have all the features but it does have the ones you need, is better packaged, smaller, more solid and a lot cheaper! If you do want the extra features I guess you could buy the MS-IBC but I havent tried that.

you could do a lot worse if your in the market for an EBC, im well pleased with mine
