I got my Bolly F3A Standard gear from Aero Products:
http://www.aeroproduct.net/
They were allot more expensive than the ones you mentioned ($50 something I think)...They are pretty kewl and more than enough for these little planes...
I didn't ask them but Aero Products may also carry the Bolly wheelpants?? The Bolly wheelpants are CF but I believe they are painted from the factory (not 100% positive on the painting)...I wanted the bare CF rather than painted so I made my own...
I've got some molds and I could make you a set of wheelpants if you wanted...Shoot me a PM...I gotta make another couple sets for myself too...
Please report back if decide to go with the Hobby City gear...(Are these the ones your talking about?? They look really Nice!!)

Have Fun...
