As always be sure o look at compatibility with your theme and also reviews on the plugin and lastly if its kept up to date.
also with envato (code canyon/themeforest) dont forget to also purchase the support option with any themes you purchase, this is so they when these themes are updates etc. you will be notified and be able to upload the latest update.
