favorite scale to model in

1/35 Armor first, then 1/72--although I will say that the current trend of Dragon using that one-piece "DS track in their 1/72 kits has seriously turned me off. I HATE one-piece tracks that you can't sag or model as knocked-out.

I have no interest at all in 1/48, and as far as 1/25, or 1/16, well, I simply would have no room to put the bigger scales anywhere.

I build 1/48 aircraft. 1/48 is big enough for nice detail work, yet small enough to display.

I have also built about a dozen 1/32 scale all of which are hanging from the ceilings of my boy's bedrooms.

I like 1/350 ships,1/700 is just to small for my fumbling fingers.

1/48 aircraft over 1/72 for the same reason........1/32 nice but you run out of display space real fast.

1/35 armor for all the selections,although I really like 1/48 but choices are limited.

About your other question.....need more info,Maybe the quality of the manufacturer,or one might be a "premium kit " with extras,but really cant say based on the infoo.
