Did my class 2 with DLT many moons ago. Good little firm, reasonably priced too the last time I checked. Must bite the bullet and get my class 1 done soon.
I went with DH Jones in magor. I live in pontypridd but after going down there and speaking with Dave I decided to go with them over the other local trainers nearer to home.
I know they have had one or two of the instructors retire and replaced since I took my tests.
