The TA is a fantastic option at least for me.  50/34 compact doubles
are almost literally a dime a dozen these days.  To try out the
compact double thing I bought a square taper Campy Mirage for $30 on
ebay, NIB.  The key things for me are:

comes in 172.5
takes a 29 or 30 tooth small ring
looks appropriate for whatever bike I am running
doesn't completely break the bank

The TA is a great option, but the pieces really do add up in price

$250 for arms
$90 for a spider
$84 for a 46 ring
$42 for a 30 ring

That's $466 without a bottom bracket.  Add a Phil Wood BB and some tax/
shipping and we're talking a $700 chunk.  I'm sure it's worth every
penny it costs, but that's a lot of dollars.
