I've been working around the 100 (and not 800) keywords issue by using the Google Keyword tool to generate keywords and then import them into Market Samauri.
For those of you who aren't familiar with this process here is how you can do this:
Goto the Google Keyword tool
and log in.
Click "Advanced Options and Filters" -> For Location/Language use "all countries" and "English". You'll get up to 800 with this option. By selecting a country you will be returned with less.
Click the drop down menu labeled columns (right side) and uncheck all of the boxes so only the keywords are visible.
Click the download icone & save the keywords as a .csv file after you have searched your phrase.
Start a new project
in MS & goto the Keyword Research. Click the "Import" button located below the box where the generated keywords would normally appear.
There's no need to click "Generate Keywords" since you already have them.
Go into Keyword Analysis. You'll have 800 keywords with no traffic data so this will take longer than usual.
Make sure the challenge filters are set and uncheck everything but SEOT & PBR. Click "Analyze keywords." (I uncheck SEOC temporally since they are not filtered yet & it more than likely adds time and wastes resources--unfiltered keywords.)
You'll be asked for a captcha or two if you have a lot of keywords.
Once this finishes check the SEOC box and click on Analyze Keywords again to get the competition data (this will be much faster).
Keyword Analysis will take longer but to me it's worth the extra time.
