In no particular order, I have always gotten good service from the following
Internet dealers. I seem to always end up ordering things that are back ordered from Roll Models, and Great Models, so my receipt of the items takes a little longer..
some take a little time to deliver, but then again it all depends what they have in stock,
and how willing I am to wait for them to get what I ordered from their distributors:
Roll Models---- excellent, although you usually have to wait, Emails you, after placing order, with receipt of order, doesn't charge your credit card until items are shipped.Emails you when shipped, with tracking number, and arrival date. Shipping can sometimes take several weeks depending on if in stock or not.
Great Models---- Service has improved 100% since they updated their site and server. Always gotten decent service from them, now it seems to be outstanding, although their in-stock showings seem to be a little off, it is understandable that if you have only one in stock, and three people order it at the same time, two aren't going to get it. Delivery, like Roll Models can be a little slow at times, sometimes taking serveral weeks.
Hometown Hobbies---- Bill Wolf is a gentleman to deal with, what more can I say
Squadron---- 99.9 % of the items ordered arrive within a week. Comsale items are usually all in stock.
Accurate Armour---- Fast shipping from UK, usually arrives within a two week period, always gotten what was ordered, with no damage.
Aeroclub Models--- Another UK dealer, again fast shipping, got my last order in a week.
Hannants---- Good service, always got what was ordered, in a timely manner.
Alanger----- Well, Max is Max, either you love him or you hate him. Always gotten good service, good prices, and he throws in a free kit to regular customers, plus his sales and discounts can't be beaten with a stick. Usually shipping is within a week to my door. Just needs to improve packaging, and better TAPE..... it's always broken when it get here. No kit damages, just the Damn tape is broken, and one day kits will be missing..... LISTEN UP MAX..... BETTER TAPING OF PACKAGE!!!!!!
Flightdec Decals---- Nice folks to deal with, will call or email you on out of stock items and ask if you want to wait for a restock. Also take paypal.
I could list more, but it would just become a internet informerical....
Model Expo, was another good dealer, but they seem to have even dumped Tamiya stock. My last venture to Model Expo showed that most of the Tamiya stuff as being out of stock, and prices at give away prices.
One thing I have learned from shopping on the internet is patience, I can instantly buy what I want or need, but have to WAIT for it to arrive, and that out of stock, and back order are pretty common.
" Boy did that sale ever !@#$%- off my wife 
She didn't know how much was spent until this "box" came in the mail. (..ie more like ice chest box....) I had a clear rational..... "IT WAS A SALE!!! "
