I would say it really depends what you're after as an end result. If you want a Zetec turbo, unless the car is already running a Zetec Turbo there isn't a whole lot a cab running a CVH on MFi can offer you. If it's running on Konis with decent brake upgrades it may be worth it, but his tends not to be the case with cab conversions. Also, if it's running MFi and you want any kind of power then you'll be rewiring the car.
If I were starting again I'd be looking for a nice clean XR3i EFi Cab. Then work up from there. Shouldn't break the bank, your choice of CVH or Zetec Turbo, Zetec > MK4 has been done plenty of times, minimal rewiring if you go CVH, a little more rewiring if you go Zetec.
To get to where mine is today I broke my ERST for parts, I didn't quite cover what it cost me and I kept the interior, running gear, turbo, engine and gearbox, probably lost me £1000 all told. I paid £650 for my cab and I spent £600 getting the bodywork tidied. I spent countless hours refurbishing the ERST running gear as I wanted to retain the rear ARB from the ERST. I spent a ridiculous number of hours refurbishing the EFi wiring loom I bought, but it did work perfectly first time and hasn't missed a beat. I had to lay out for Konis, brake upgrades, polybushes, EFi parts, ECU & Chip, ally rad, Front Mount Intercooler, Mongoose Exhaust: you can probably add £2500 for all of that. It all adds up (albeit over 10 years
), but I built it to my standards, wiring is spot on, and if you added up my hours I dread to think how much that could cost.

The end result makes me smile though and last year it did 2,500 miles with a lot of thrashing!
