My advice is always to get the best possible frame for your budget and worry less about the components. The frame is the heart of the bike and EVERYTHING else can be swapped out if you choose.
Also, don't be fooled by what you "think" is a complete grouppo. Most bicycle manufacturers hide the cheap parts where they think you won't notice. Check out the Bottom Bracket, Headset, Hubs, Stem, Cassette and Seatpost. These are the most common places to find cheap parts that are poorer quality and which are very HEAVY.
Just because it has an Ultegra rear derailleur does NOT make it an Ultegra Grouppo. In fact almost all manufacturers upgrade the REAR Derailleurs to 1 or even 2 levels above the rest of the componentry found on the bike because thats how the bike shops sell them to you "See this bike has Ultegra" and they know the consumers have been trained to look at the rear derailleur to identify the parts grouppo.
In addition, most manufacturers have their own brand of "House" parts that they integrate into a parts grouppo to keep costs down. TREK (as an example) uses either their "Icon" stuff or the "Bontrager" stuff to fill out a grouppo (check out the cranks, stem, seatpost, bars and wheelset on the Trek 1500)
So get the best frame you can afford, check out what's really "under the hood" and then ride, ride, ride and be happy with your new bike!
Hope that helps.
