You have made the right decision like many others Squiff,I really like the layout of your new site,beware Fleecebay are tightening up on links employing a team of people to scan the listings,so use it while you can,greed has badly set in and I think that this will be their downfall,what they have failed to grasp is that small low priced items have now become totally un-viable there,coupled with the postal increases there just has to be a limit imposed on what they can charge.
I like the tutorial on re-scribing panel lines,excellent,and also your gallery pictures as well,why not try and link these to a particular kit that you are selling ? you could build up a library of detail images from museums etc,even place the respective kit for sale at the top of the page ? just an idea for you to consider.
Anyway good to see that you are growing steadily,as long as you can retain that personal touch then you will be fine.
