砌板is not a problem at all. The shops will recommend you the appropriate ones to choose from, AND glue the rubbers for you.
2 of the shops I use, providing good services (including gluing) and recommendations are as below:
New HK Star in Wan Chai, many choices,including second hand ones.

先進乒乓用品. Advance Table Tennis Equip. (Siu-Sir)

筲箕灣 天悅筲箕灣廣場天悅廣場1083A鋪
(you must call him in advance as he is not always at his shop. He is distributor of Milky Way brand in HK. Milky Way products follow closely those of Butterfly and other world famous brands, at much lower prices)
If you are new and want something decent, try Butterfly blade plus Butterfly rubbers (have them glued by the shop as value-added service to you free of charge).
