Thanks for the help, kcarlile, bdpf, Dr.House and Alan.
Alan, your description on VP180 is sooo alluring which makes me decide to purchase this model rather than VP150.
In my experience and deciding on two models that I think I would enjoy, if there is going to be a "what if" going on in your mind about the VP180 if you purchased the less expensive VP150 then go with the VP180. In the short run you might think you are saving money but in the long run you wind up spending more money than if you went with the VP180 in the first place.
