My personal opinion is that for home espresso, the whole T-type, Fluke thing is so far over the top that even binoculars won't see it, you'll need the Hubble.
The Scace thermofilter is designed for qualifying machines for Barista competition. This requires high accuracy and repeatability to be fair and meaningful when comparing machines to others measured at other places by other meters. At home on the other hand, if your readings are slightly biased, the bias will be repeated on all your measures, so as far as understanding the effect of changing temperatures, it will make no difference
You can get K type thermocouple digital multimeters, with the TC for about $15. You can get 2 and 4 channel temperature loggers, that talk to computers via USB, for around $120. These will only be plus or minus 1/2F providing you've calibrated; but they won't be Fluke or T type. Google will turn up lots of good alternatives. The cost savings are quite dramatic.
On the other hand, while your espresso will not be improved by high end measurement gear; it may give you peace of mind knowing exactly how hot your good, bad and ugly shots are.
