Printer recommendation

I've been using 2 Epson printers for some time (R200 & R300) I modified both with the waste tank mod. I have low ink reset free chips placed on all 6 clear refillable cartridges. I use the Stratitec ink and had a color profile created for both printers for both matte and glossy paper. Colors are spot on and I have never had an issue with either printer.

I am now at the point where I want larger format printing, archival ink and maybe better B&W output. I would like something that can take clear refillable cartridges similar to what I have on the R200 & R300 series so that I can use pigment based bulk ink for refills. I am agnostic to brand but the clear refillable cartridge is a must as I have been able to save 80-90% on cost of ink with the current system.

Budget is less than 1k. Any recommendations appreciated.
