What do you like? Do you require a CUSTOM solution or a more budget friendly template. Builders can bridge the gap. Every WordPress worker has a favorite set of tools. The set up at WebProvements is more future proof than some. If you want something totally premium and maintained for years to come…Awesome!
If you have a FREE Theme from the repository there is a likely chance that it will be abandoned and not maintained. If your theme is not maintained by the theme developer, it is only a matter of time before it stops performing for you.
Even if your site/plug-ins and server are being maintained, an abandoned theme will eventually need to be replaced and this can be a costly upgrade.
