Hey cool! I'm glad all that info is proving useful. I have to say that the tablet I mention I bought has been serving me very very well. It isn't extremely portable do to its size, but the available drawing space is worth it. I've traced a few hand drawings thanks to having that space available. Interestingly enough the tablet is the same size as my wide screen laptop so that fit very nicely together in my bag.
Excellent map and excellent mountains... Very impressed with the individual time you took to do each one... and for the forests... i'm all eyes and ears for how you did those ... what size are you working with for the over all map? What is the scale of the map?
I had a Nisis A4 tablet for a while but never really got into using it. I got an A6 Wacom Graphire4 for christmas and it is fantastic. It cost £80 (which is around $160 these days) and it does everything I need, with the exception of having tilt sensitivity. As Wacom discontinued this range and brought out the Bamboo range I guess the ebay cost for these will come down significantly. The fact that the pen does not need batteries, or replaceable nibs, is brilliant. The drawing space is more than enough which was quite a surprise.
