couple of quick p-cut questions, spares/servicing etc?

[gavtheoldskater]

so, after going round the houses after a cutter and deciding to hang out for a graphtec... a pcut ct630 came up for sale locally at a very cheap price so i thought i'd give it a go.

it all works fine, but if poss i'd like to give it a little care...

can anyone tell me where i can get a replacement cutting strip as i'm struggling to find one.

similarly for cutters can anyone recommend a source/seller as against whatever comes up on ebay.

does anyone have any advice for maintenance; tensioning springs, squirts of teflon lube on moving parts etc?

thanks
