I found a UK seller on eBay with both the Bandits High Starter Set and the BH Boosters for a reasonable price: $26 CND ($19 US) including shipping from the UK.
His feedback is only 97%, but I've decided to take a gamble and order from him. I already have both starters and several boosters, but I figure it can't hurt to have the extra maps and such for a good price.
I'll post an update when I get the items....
The seller also has the Angels 20 Starter and A20 Boosters, but he wants a lot more money for those... ?
You can see photos of my three boosters in Toyama's Unboxing thread.
I received: - a P39 Rookie (my 4th!), a Tojo, an MS.406, - a 520 ace, an FW190 Fulger, a white Zero rookie, - a 2001 CB, a Romanian IAR-80, and a Sturmovic!
This seller was not able to deliver the Bandits High Starter Set after three weeks. The seller then asked for another three weeks to ship, and I said 'no' at that point.
I am happy with the delivery of the Boosters, however.
