You will not believe this stuff!  The set pictured below retails for 10 dollars!  Words don't do justice, so check out the links below, and TELL YOUR STORE TO GET SOME.
Or if the locals are dragging their feet,  pop over to The War Store and give 'em some well deserved business- they have a flat shipping rate, so order in volume :)

HEXAGON AND PLATFORMER SETS- by TEHNOLOG
The source of this madness- mother Russia...


MUST BUY- The Chemical Plant is AMAZING, a box chock full of tanky, pipey goodness!

Be sure to check out the Tehnolog Website for other sets too!  Check out the TECHNO BRIDGE and MAGE GOTHIC RUINS- some stores already carry these sets, so ask around!

IMEX- PLATFORMER AND HEXAGON SETS
See, these guys really claim to carry the stuff.
IMEX- NORTH AND SOUTH AMERICAN DISTRIBUTOR
Americans, point your local retailer here...

Pegasus Hobbies is also involved in the distribution somehow,  though I didn't see them on their site anywhere...
PEGASUS HOBBIES

And, according to the box, the European distributor is Pocketbond LTD, P.O. Box 80, Welwyn, AL6 0ND, England.  Sorry, no website...

UK BUYERS-   WARGAMES WORLD  may carry the Hexagon set,  so you might try them.
