For better or worse, all of the major qualitative analysis programs are very competitive with regard to the range of features they offer and the prices they charge. But you might look into Dedoose, which is cloud based, so you don't have to worry about compatibility, and which charges by hour of usage.

Other major qualitative analysis include MaxQDa and RQDA.

There is also WeftQDA which is a free software. You will find it on Google.

Given that you have concerns over cost, I would still offer Atlas.ti as an option that is worth looking into. As David L Morgan has noted, most software these days are fairly similar in terms of features, but I have found Atlas.ti to be fairly comprehensive and flexible, and very powerful in its data organization features.

Atlas TI is another software program for qualitative data analysis. However, I am unsure of pricing.

MAXQDA and Atlas TI are some I know of, that could replace NVivo for qualitative data analysis, including TA.

I have students use Dedoose. They have liked it.

Atlas t.i is another software for coding and analysing wialitative data

Eric's suggestion of Weft QDA is a good one, though this software is no longer being updated/supported/debugged, so it's definitely a "use at your own risk" thing. I gather that there is now a free version of QDA Miner ("Lite"); here is a link: http://provalisresearch.com/products/qualitative-data-analysis-software/freeware/

I do not know how powerful/useful this will be compared to what you've been using. Depending on your research questions, you also might find Pennebaker's Linguistic Inquiry and Word Count (LIWC) helpful.

I suggest you MAXQDA and ATLAS.ti. However I prefer MAXQDA.

I'm currently using ATLAS.ti and I must say, it's quite helpful.
