@rsa - I do not own, and have not heard the RM 1.3. However, I do own the Pro-Ject Carbon Debut Esprit SB. I'm pretty happy with it at it's price point. It sounds very good, but is just a little noisy relative to much more expensive TT's. The RM 1.3 is less expensive (on-sale now for $369), has an aluminum S-shaped tone arm instead of the carbon one, a minimalist plinth, no speed control and no dust cover. For my money, the Debut Esprit is a better value. I won't buy a TT that doesn't have a dust cover and buying a custom acrylic one for a table like the RM 1.3 would blow the budget for me.
Good luck with your foray into vinyl.
