not uncommon ... IF can you afford the bass without financially hardshipping yourself or your loved ones, by all means go for it ... for my situation, I have found the key is to buy used, and buy smart ...
... unfortunately, this feeling will hit you again, and usually when you are least expecting it ... when buying used, you have the peace of knowing that your last purchase can be 'relocated' to accomodate the new object of your desire, without much of a financial blow ...
... it is kind of a revolving door once you get started .. but if you do it right, it doesn't need to cost all that much ... the only ones that usually end up making a bundle $$ are the FedEx's, UPS's and USPS ... JMHO
