I can jump in for Spiff here, and let you know that there is no problem using the digital meter as opposed to the analog one. Yes, the analog one is more often recommended as the one to get (I forget the reason why but it is not because there is anything wrong with the digital), but the digital is also preferred by many people and will give you fine results. Don't worry about it. I use the digital and it works great for me.

Don't forget to set it to C weighting and slow response ideally.
