Dual Duct Portable AC Units

[hank b]

I cannot install a window unit without destroying the window sill so I must buy a portable unit. I am looking for a dual duct unit without a reservoir that requires emptying. I have identified several units which seem to meet my requirements:

SoleUSAir MAC-10K
SoleUSAIR MAC-12K
SoleUSAir LX-100 *
SoleUSAir LX-120 **
Toyotomi TADT32GTM
Danby DPCA12031

* appears to be same unit as MAC-10K
** appears to be same unit as MAC-12K

Can anyone comment on these?

Are there other units that meet my requirements that I should consider?

Thanks,

Hank B
