The value is going to range across the board...
The reason is because a LLLL.com with 1 vowel, can be pronounceable - IE - Slud.com - 1 Vowel, easily pronounceable. I believe a name like Slud (which I just randomly chose) would fetch mid-high xxx on the reseller market, perhaps even hitting the 1k mark.
Now, a name likd Bodg has very limited value. Although it has I believe all premium lettering, it is what I consider a Bastardized Pronounceable - meaning - if you force it , it in a way that grammar doesnt allow, it is pronounceable. In this case - its spread into 2 distinct words - "Bod" and "G" - or Bodgie....
These domains range from registration fee to low xxx with the right lettering and combination of words.
Now, a domain without a vowel, and all premium lettering would fetch mid low to mid xx resale. However, these names are widely abundant and often times can still be found for reg fee when they drop.
The LLLL.com market is tricky, and very few people have a complete grasp on it. But the cream of the crop right now are CVCV and VCVC - if possible, I recommend going after these while they are still within "reason".
Good luck,
Justin
