Prices for T-discs aren't bad. I bought a pack of Starbucks House Blend, 3 packs of 8 in one package for about 11 dollars. Hot chocolate and green tea and others are about 3 something for an 8 pack. You can buy these virtually anywhere, walmart, cdn tire, superstore, london drugs...
I just recently got the T-65 and it's great so far. Very minimal effort to make a beverage and the coffees so far that I've tried smell good and taste just like if you bought it at a Starbucks.
The only difference in the T-65 is the LED screen that tells you what's going on and when the drink will be done, so if you don't really care for all that get the T-45 which is exactly the same but without the LED.
The only downside is I wish there were more variety of t-discs. In Europe they have way more selection.
