I tried CEGO some years ago when they had the two shirt min for first time customers and I am rather sure Carl is about customer retention at the end of the day. I have tried the online services, but the difference generally isn't more then 40-50 bucks and I get to handle the fabric, which I consider very important. $140-160 is some solid material to be had at CEO and I can't say online MTM delivers much quality below $100. So actually not that far off.
Daffy's on Broadway in the Financial District has two interesting sports coats. I would have picked one or both of them up, but just couldn't justify it to myself.
1 Pal Zileri Cashmere Blazer 42L $399 discounted by 20 or 30% so closer to $300
1 Caruso 50/50 Cashmere Silk Blazer 40R $349 discounted by 20 or 30% so closer to $275
To add, I'd say pick collars that are slightly larger than the minuscule trend that has kind of taken hold. The Italian makers such as Borrelli should make something along those lines. If you do go MTM or custom, I think they will also be able to use a stiffer the interlining on the collar band, which should help too. Carl from CEGO would definitely be your best resource.
