Kiln suggestion / recommendation ?

Presently looking to purchase a Kiln so that I may do the following:

- Precious metal / Jewelery / PMC clay, etc...

- Enameling on Copper / Silver / Gold etc...

- Glass slumping and fusing (largest piece would be about the size of
a breakfast bowl)

I would prefer a kiln with a 'side opening / swinging door and with a
window or peep-hole if possible.  For convenience sake I would prefer
it to be 110 volt.  If that's not possible, 220v can be made
available.

Most of the kiln's use would be for slumping and enameling

Money is not an issue, but I don't think I could justify spending any
amount over 5k.

Any suggestions or recommendations would be helpful......

Cheers,
