some advice please

i own a mk2 white 2 door rs 2000.
i've always wanted one and to get one in the colour i wanted too is a blessing. i bought it about 4 weeks ago and have been miserable from day one.
it has had an efi conversion and suffers a surging/cutting out/idling problem that nobody can seem to eliminate. i've spent hundreds already. i can't find parts for it nor anybody with knowledge on it.
i find myself having to make a decision. do i convert it back to a carby setup, or do i just sell it. my considerations with both of these options are:
- if i sell it, will i ever get a hold of another rs 2000 white 2 door for a reasonable price in reasonable condition again.
- what kind of work is involved in converting it back into a carby setup. it isn't the original engine. it has the 205 block with a standard pinto head as far as i know. i do have the original head though.
any advice greatly appreciated.
