Is This a Good Deal?

I am contemplating a new purchase.

My LFS is offering to sell me a complete 150 Gallon tank (All Glass
brand) with finished cabinet and top (with the lights installed in the
top).

The price includes everything except the fish (wet/dry filter, UV
sterilizer, skimmer, everything).

The setup is going to be a fish only tank. With a tank this size, I
can eventually have a dramatic community of relatively large fish.
And, with the amount of space in the tank, hopefully I can keep the
aggression to a minimum.

The dealers price is $2200 and this includes him delivering it and
setting it in place. I will fill it and get it running so I can cycle
it.

He still believes in cycling a tank with damsel fish. What is the
consensus? I know, years ago this was the way we did it. But, there
are some products on the market that are supposed to speed the process
of cycling the tank. Do these work?

Thanks.
