Wine cellar vibration

I am a relatively new wine collector (6 months) and have already purchased one wine cooler (35 bottle) and of course I have already outgrown it. I am purchasing wines that I want to collect. I have been buying 2000 and 2003 ports as well as 2000 and 2001 Barolos. To me these are expensive and I want to take care of them. The cooler I bought is a decent one (2 zone - but unfortunately the larger section is for the whites and I really don't collect whites) but it is a compressor and not thermoelectric.

Here is my question. I am getting ready to get a larger one, probably in the 200 plus range. Generally, Thermoelectric are not made larger than 40 bottles and then they become very expensive. I have seen some coolers in the $1000 - $1500 range but they work off a compressor. Is buying one of these going to have vibration that can really negative affect a port that I plan to cellar for another 15 years? I will be keeping it in my basement which has a temperature around 70 degrees, but I have no humidifier in my house.

My other option is to make a wine cellar. I have been reading about the vapor barriers and insulation and I feel I could do it, but I would prefer to just buy a cooler. A friend told me that even the slightest vibaration (maybe unnoticeable, but at a molecular level) could destroy my ports.

Any help would be very appreciated.
