I don't think glue is bad... I guess the clean up is easier with tape, if you have heard bad things about glues then just use tape.
There are a lot of different glues available you will have to find wich one works for you, I am currently using UltraHold and I don't think its that bad.
You can also use ''got2beglued'' gel for your first attachments I heard its real easy to work with.
