I've been considering getting a SGII or the UG for my 2001 Outback.

I've been using a cheap sunpro vacuum/boost gauge for the last few months. Although its useful, I feel an actually fuel calculating/estimating device would be much more helpful.

Here are a few of my questions:
1) Both give MPG output, is one better over the other? An example UG refreshes twice fast vs SGII, or SGII is 2-3% accurate vs 4-6% for UG.

2) Are the gauges backlight? It looks like the UG would be night visible, but I'm not sure about the SGII

3) Are there more/less features from one to the other? To me it seems like both offer everything the ECU data port has to offer.

4) I know the SGII has been a long time favorite, but is it really worth almost $100 more than an UG? I mean where is the added costs?

5) Easier plug and play? SGII seems like it needs to be calibrated to the vehicle. Does this change matter if you have extra people in the car (weight input, etc)? Does the UG need to be calibrated just the same?

Would like some intelligent answers that we're all capable of forming! I think both gauges are great, but going into holiday season working in a questionable stable job, the price tag on the SGII has me slight more interested in the UG. But truth be told, I would like the better product.
