Hi Mark...As you can tell by the responses there are a LOT of people who have quit and come back to the hobby. I quit when I went into the army and started again when I got out. I quit again when I moved back to Germany and then started and quit several times with years in between. Now I've been at it again seriously for for about 10 years. You are never too old....the styrene always stays in your blood.
Like you, I have a job and family and little time so I build mostly out of the box...but with todays kits, if you are just building for fun, there is really no need to do a lot of aftermarket parts.
You said you want to do the best job possible on your kits so read the online reviews available here and on other sites and choose the most accurate kits. With several companies releasing kits of the same subject it's not hard to find a model that meets your needs.
One thing that has changed dramatically since you've been away from the hobby is the price of kits. I know in England th price of a kit is a much more than in the States (for whatever reason). That might also affect your decision to buy AM parts.
I do buy aftermarket stuff...I just got Friul sprockets, Modelkasten tracks,Tank Workshop wheels and an Eduard photo-etch set for my ancient Tamiya SdKfz 7. The aftermarket stuff probably cost me three times what I paid for the kit originally but I really wanted to build a fairly accurate kit. On the other hand I bought the Trumpeter early SdKfz 7 and paid the same price as I did for the Tamiya kit and all of the AM stuff together...it's a much more accurate kit but still has room for improvement.
It's all about budget, available time and the expectations you have for yourself.
I build mostly out of the box and for fun...but in the end I want fairly accurate model to display.
Good Luck and welcome back to the hobby.....if I were you I would set aside at least a SMALL portion of your paycheck for rent, food, utilitities and other non-modelling related activities. Thank goodness my wife works!
It's like an addiction....with the number of new kits released every week I need to find a second job and another set of hands to buy and build all of the kits I want.
