IMHO an SPG + wrist computer is inifinitely superior to the analog cluster(f... *ahem* ). Within recreational limits, a backup depth gauge is somewhat unnecessary - you'll only need one when you lose your buddy AND your computer dies mid-dive AND you have to make an ascent without any references... but there are ~$50-$60 swatch scuba watches on ebay with a depth gauge built in, or an analog gauge could be picked up at a similar price and stuffed into a pocket, if you want one.
