Cygnus 2112 you are a lucky ^*+^£.
. I've scoured our local Borders with no luck.
There was supposed to be a reprint celbrating the 25th anniversary out. However, there have been production problems and they're thinking now it will be out later in the year or early next year.
In the meantime, you can try to pry one of Cygnus' copies out of him or keep searching the web. If you're not very familar with the gameplay you can go over to www.classicbattletech.com
an go to the "Leap in!" section. They've got a printAble version of some Quickstart rules. (see my recent session reports.) They also have the larger Intro Rulebook (similar to the one that comes in the box.) There are also record sheets for the mechs. The only thing missing, maps. But you can still find those on eBay & elsewhere.
While the minis are cool, they're not absolutely necessary to get your feet wet.
When you go to that website you'll see that there's a pretty active community.
Now Cygnus, I would be interested to know how much one of those box sets would bring you on eBay. You could sell them both, save the money and get some cool new stuff in a few months.
Follow up edit: I looked up 8 different locations around the country (looked up zip code of places I used to live, searched Borders inventory for the area and then put the "Likely in Stores" on a list to call.) and the first one I called said they had it and are shipping it to me for a $5.00 fee. They weren't sure about sending it to Canada. You might want to try the same thing.
