Well, I pulled the trigger on my order from Nal just now. Totaled up to just over $40, but the sale got it for $32 (plus shipping). Here's what I ordered:
Coffin Stand
Dragon Brazier
HA092 - Sand Blasted Pyramid
HA093 - Egyptian Tower
HA094 - Egyptian Temple
HA095 - Egyptian Basic Block
HA099 - Egyptian Fountain Accessory
HA200 - Wall Builder
HA250 - Small Brick
HA300 - Station Builder
HA320 - 5/8" Pipe
HA321 - 3/8" Pipe
Med Lab Interior - Main Pillar
Sci-Fi Barrels - Set of 10
Starship Interior - Power Nodes
The items marked by HA### are "one-casts" - basically, Nal fills his mold with plaster once and you get the blocks. This is ideal if you want to try out the blocks from a particular mold before buying the entire thing or if you only need a few pieces from the mold. The other items are bits of terrain that have been built using primarily HirstArts blocks but that Nal then made into a single piece and cast whole. They are scaled for 28mm wargame mini's, but in a lot of cases, they look just fine next to action fig's.
I'm evaluating the Egyptian blocks for suitability in Mos Eisley type dio's, so y'all get to see how those come out. The blocks in the "Wall Builder" cast look like they scale out a little bigger than cinder blocks and the "Small Bricks" measure out to almost exact scale size for standard bricks.
If you want to see what the HirstArts blocks can do for your dioramas, I humbly
suggest you get busy and order some from Nal. Remember, use the code "laptop" during the Order Confirmation stage to get 20% off your order. And telling him OutlandStation sent you would be nice, even tho I don;t get anything out of it!
