do a search in CS and u'll find www.gloryworkz.com, art friend(bras besar, ngee ann city), shop in citilink, konota(peninsula), colourlab(adelphi), beautiful memories(stamford house) and also Keeper (CS nick) selling traditional black albums, acid free paper, etc etc.
Is "unique" a specific brand? Otherwise, there's quite a variety of inexpensive photalbums e.g. at the Big Book Shop at Clementi Central. From 4R to >A4, white pages or black pages, slot-in, plain cardboard or adhesive foil, with bound backs or extendable (screw-mount binding) etc.
I greatly prefer "free-form" albums that let me orient/arrange pictures to my liking. They usually also look less plasticky than slot-in albums.
