I have scratch built a number of boats, but have also built 3 kits, a Billing "Nordkap", a Model Slipway "Sentinel", and an Artesania Latina "Amsterdam". The Amsterdam was my first model boat after many years flying R/C aircraft, and I thought it an excellent first choice - for me, anyway. Model Slipway kits are extremely good, as many Mayhem members will tell you, and Billing kits are very good too, but are probably best tackled after gaining some experience. Have a good look through the posts here on the forum, I'm sure you will find lots of info, and keep asking questions, there is always someone ready to offer help. Joining a club is a great idea, as there is nothing better than face to face discussion.
As Frank says, knowing what type of boat you prefer helps others offer suggestions.
