Steve,
The modelmakers in the area, along with almost every other in the UK, have changed from buying from the "little shop around the corner" to buying on the internet. The model shops are now few and far between.
For sailing waters, the Heywood club, I think have restrictions on their lake sailing times. The best nearby water is the Bury club, who have 24/7 access to their lake. The lake is now shared with fishermen, but this hasn't caused any problems. Both clubs meet on Sunday mornings, but as previous at the Bury lake, the times are to suit yourself.
The Bury club lake is BL9 6NG – Clarence Park Lido, off Walmersley Rd,. Bury. Further details are in the link to club's website (directions are in the "about us" tab). The lake has good all around access with a couple of artificial islands in the centre, so boat retrieval is usually ok in event of any problems.

Here is a link to the Heywood club's website which details the time allocations.
