Born and raised in the East Riding, save for degree studies in the big smoke. Unfortunately almost at the opposite end of the Tees-Exe line for the GWR!
Currently building up (hoarding) my fleet, and taking my first steps in scratch & kit building, via modifying RTR! The dream? A secondary GWR mainline in the winter/spring of 1946/7, with plenty of operating interest, and justification to run all classes of Swindon's finest!
nice to have but not critical, I have one and havent used it in the past year on any of the etched kits that i have been building, or the RTR coach conversions.
Personally if it was a choice between a Dremmel or more kits, I would go with the latter.
If you do look for a hand held then perhaps consider Proxxon. A little more expensive but high quality. Check the reviews for each brand for comparison.
