Hi I'm new here . But I was wondering if there was somebody I could answer a couple questions for me. I have an older coast ball with the TSPA1 board. As you know most of these boards have been discontinued and I was wondering if it would be a viable option to just replace the whole spa pack with something new or even a different brand or if you would just recommend sourcing out a replacement board as I'm pretty sure mine Is in need of replacement. If a new spa pack is in order what do you recommend ? I was looking at a BP 501 retrofit kit because I like the Wi-Fi feature. And was wondering what you guys think. thanks in advance
