Low prices on high end items, low or zero feedback always get a red flag. I usually watch the item and see if there is any other activity or other sales. In most cases if they are only selling one item I'll pass.
Had a problem last x-mas. Picked up a tiger II from Germany. By the time I checked on it, the kit had been stolen from my porch. I must say the German seller helped recover the funds from DHL international. But what a hassle.
I hope Paypal put a hold on the funds, otherwise they are gone.
sorry and I hope you get a full recovery
