I use a lot of the Xforge bases and the seem to work pretty good to me. I was one of the folks that requested they list them on their site. It's a pain to epoxy them to the base but once it hardens they're on there for good. I use the quick setting J-B Weld.
I should mention that Ghukek has all of his ships on XPForge as well. He has his earlier models on Shapeways and XPForge. But I think he is only doing his more recent ships on XPForge. They are also very nicely done and I bought several when I ordered aircraft.

ghukek has posted the IJN battleship "Kii" to his Etsy site. The only significant difference between the late war Yamato and Kii was the replacement of the 5in tertiary with 3.9in AA battery. The 3.9in dual-purpose gun was significantly better as an AA weapon than the older 5in gun. Kii was about 30% completed when its construction was cancelled.
Note that the description says it has a "6in tertiary." This is a typo. It has the 3.9in guns.
