The Fine Molds Star Wars kits are in 1/72nd scale not 1/48th.
The kits available at SSM are from the same masters the SMT used. They were created by Alfred Wong and they are decent kits. While the original X-wing kit from MPC/Ertl was about 1/48th scale, they also made two other verisions, a snap together kit that is close to 1/72nd and a lights and sound version that is close to 1/32nd.
While the 1/48th scale stuff is nice, I would be happy if Fine Molds would release more in any of the Star Wars universe. They do a great job with the detail and it's nice to have everything in the same scale.
