I don't no how you feel about buying from overseas but if you go to -
They are selling a pair of HENG LONG PANZER 111 Wheels for 2.95 Euros which is $3.25,
They are also selling a full set of PANZER 111 Wheels for 12.95 Euros Which is $14.20 Plus Postage.
They take PAY-PAL and if you do decide to buy from them you must remind them that you are ordering from the USA so that you are not charged VAT (Value added tax)
I bought a CLARK Board for a Tiger 1 from this dealer NO PROBLEMS AT ALL.
