Thank you all so much for your replies.. the advice is appreciated and taken on board but has left me in even more confused

in that I was pretty sold on that BCD - just not sure if the repair was safe!
I went to a dive shop today and tried on the AL Ladies Pearl (not the i3) version in size XS and tbh I have never had a BCD fit me so well.. At 4ft 11 I am quite petite, and it did not feel overly bulky - in fact to the contrary of any I have worn that have always been extremely bulky for me. That said, it was not inflated, but being more of a hybrid it felt far more slimlined.. I can see however that there could be tank stabilising issues. I have never worn a ladies BCD before either and have always been swamped.
Your input on the i3 system is interesting, having never used it, it sounds good on paper, but I can also see that maybe not having an inflator button to hold but might feel a bit like switching from a geared/shift car to an automatic and so take some getting used to ..to feel in control. I guess this is a personal preference and I wont know until I try. I had read that maintenance was easier .... "
The i3 does not utilize pneumatics or hydraulics to activate the Flat E-Valves. Therefore, there is no possibility of failure due to leaks. Using push-rod technology, as found in aircraft, the design remains simple and robust."
I have had more feedback on the repair - it was apparently minute bubbling rather a tear and the guy has said that the patch was done by the dive shop and was much larger than it needed to be and it was tested after use. He has also said it looks worse in the picture than it actually is.. I had read the ad to mean it looked worse than in the picture. Anyway bidding ends tomorrow, as suggested I will set a maximum bid at a sensible level and account for a full service cost as well.
In the UK these BCDa are around $600. I have almost been prepared to buy a new Pearl i3 - so I am hoping I do get this one at a good price - that way if I hate the i3 system and find I personally find it over bulky I won't feel I have wasted my hard earned money at the expense of some other kit.. if I dont win the bid, then I will try out some other ladies bcds.. so any suggestions or advice on other brands would be appreciated greatly.
Is it possible this BCD does not have a separate bladder? I can find no reference to it in the specs?

Well folks - I won the bid - I didn't increase my offer after what you all said, but I got it for about $60 - so I reckon its worth the punt. I'll let you know how I get on and will get the bcd serviced and the repair checked.
