No more rep AFAIK.
Can't remember what i paid for my MF2 - was about 3 or 4 years ago now, and i got the SigCon and injectors as well. RRP is near £200, and i think i sold mine s/h for about £100.
Personally i'd ask the seller for a picture with the lid off, just to make sure its intact and no signs of something having burnt out.
Bare in mind you will need an aftermarket MAP sensor in order to use this with boost, so thats another £50/60. Personally if doing it again, i'd go for standalone straight away - but not always financially viable. But by the time you buy this, pay someone to fit it (unless you're confident with electrics - its fairly easy as long as you're confident) and pay someone to map it (again, possible to do yourself - but would suggest buying a proper AFR gauge which will cost around £100-150) - you've paid 4 or 5 hours labour.
