Actually I have a fair few Silent Death ships, though I am very interested in getting various fighter cracft from other games for use in it, such as Centauri gliders (so I can paint them like Death Gliders from Stargate) Vipers from BSG, etc. Thankfully we haven't been playing much Silent Death lately, mostly just Heroquest and Starmada AE.
I have been slowly replacing my old and tattered Heroquest set with custom parts and components, which can be fairly pricey as most of the figures are now metal, or GW plastics (which are not sold in small enough packages to be of use, so I have to try and find small sets of parts to order, which can be challenging), printing out or buying new sets of cards, etc, overall a lot of work, but it will be well worth it when I am finished. Especially since this set will be very well cared for and enjoyed for many years and my niece and nephew really enjoy the game, as I am sure my children will as well when they are a bit older.
And for Starmada, I am acquiring a Minbari fleet from Babylon 5, and my brother is interested in gathering up some Star Blazers figures.
However, someday, Uncharted Seas will make our list.
