I own two older model Samsung recievers (SIR-T151, SIR-TS160).
Has anyone any real world experience comparing these models to the newer ones - Samsung SIR-T451 and/or others ?

I would be interested to know how the the newer models stack up against the older models, particularly with regard to reception.

I generally get very good reception on my older recievers, but would consider upgrading to a newer model if it will help fix those ocassional reception glitches I get. (currently rare - maybe one or two times a month during the summer, almost never during the winter) especially now they seem to be coming down in price.
