It was a regular crystal, one that I've had in stock for a while now and wanted to get used up.
Up until now, I had no idea TCXO's were even available in 2mm x 2.5mm packages, but, you made me look and now I have a choice to make (whether to add $3 more in parts per board or not). I might reconfigure the pads to accommodate both options and see how my crystal does first before ordering TCXOs.
Edit: Yea, I will do use TCXOs. .5ppm will have to be good enough because I am not spending more than a few bucks on the oscillator. And I am too poor to order the new micros and TCXOs in large quantity, I don't have thousands laying around to waste, so I will order small and only if they sell will I order more. Probably smarter that way anyhow.
