Pros and Cons of a 30 inch deep tank!

[dbdavid]

I am in the midst of planning for a new tank and really like the look of the 30 inch deep tanks. I am pondering the following size tanks that will be starfire glass on three sides with eurobrace top:

30HX30WX72L=281 us gal (approx)
28HX30WX72L=263 us gal (approx)
24Hx30Wx72L=225 us gal (approx)

I will be using 400W metal halide lighting and a 1-2inch sandbed.

Are there any issues with a 30 inch deep tank other than needing a wetsuit to touch the bottom?

Any advice from deep tank owners would be appreciated.
